                           cope with production variations. Since a remote interface is used (Figure 1.9 and
                           Figure 1.10), the  necessary adjustments  are  executed  on-line without stopping
                           production. Those operations include:

                           1.  Adjusting the deburring angle, i.e., the angle between the border of the glass
                               and the deburring belt. The angle introduced is added to the programmed one,
                               so that zero degrees means keeping the programmed angle unchanged.
                           2.  Adjusting the  force on the belt during the deburring operation  (adjusted  by
                               position). The commanded  value is entered in millimeters and updates the
                               actual position in the direction  perpendicular to the belt and  parallel to the
                               surface of the glass.
                           3.  Adjusting the deburring speed.
                           4.  Maintenance  procedures  necessary to change the  belts after the  planned
                               deburring cycles.

                           The de-palletizing robot requires less parameterization since it executes a very
                           simple operation. Besides that, the gripper adapts to the surface of every model of
                           glass, using presence sensors strategically placed near two suction caps (see Figure
                           1.8), with the objective  of  having an efficient  de-palletizing  operation.
                           Nevertheless, the operator is able to change the velocity of the process by stating a
                           slow, fast or  very  fast cycle to adjust to  production  needs, suspend and  resume
